Palnadu Mining coverup
Illegal limestone excavations in Palnadu
Putting satellite imagery and data from government and private sources together, Sudhakar found that limestone was being mined illegally in Palnadu region of Guntur. The article showed that this was happening for 20 years. While the Mines department said 31 metric tonnes worth Rs 130 crore was excavated, a CBI investigation said the numbers could be twice as much. The scam was comparable to Obulapuram iron ore mining scam involving Gali Janardhan Reddy.
